Plot in 3D a quadratic function

Hi, I want to see this function
f(x,y,z)=x^2-y^2-z^2>=0
such that (x,y,z) in [0 1]^3.
I tried
------------------------------
[X,Y] = meshgrid([0:0.01:1]);
Z = sqrt(X.^2-Y.^2);
plot3(X,Y,Z)
grid on
------------------------------
and
------------------------------
[x, y] = meshgrid([0:.01:1]);
z = sqrt(x.^2 - y.^2);
surf(x,y,z.^2)
------------------------------
I don't know if this is correct, any suggestion?
Thank you

I am currently trying to plot 4 dimensional data in a 3D plot as well and i think one solution is to use scatter3(x,y,z,f(x,y,z)) where x y z are the coordinates and f(x,y,z) describes the size... havent done it yet but seems like it might work
